The installation of air powered pneumatic butterfly valve must be subject to vibration reduction dynamic calculation, and the effect is the best
1. The installation of air powered pneumatic butterfly valve shall be subject to vibration reduction dynamic calculation, and shall not be carried out based on experience, so as to avoid resonance, low vibration reduction efficiency and other phenomena, resulting in losses.
2. In order to ensure the balance of equipment installation, the deformation of damper ball valve damper shall be adjusted to be consistent; The pneumatic butterfly valve with damping ball valve of the same series and model shall have uniform load; Deformation F=9.8 (P-P1)/k (mm);
3. During the specific installation, the ball valve and pneumatic butterfly valve shall be installed symmetrically for symmetrical machinery and equipment;
4. While keeping the equipment stable, slightly move the position of the shock absorber to make the deformation of each shock absorber consistent;
5. For asymmetric machinery and equipment, if the centroid deviation of its center of gravity is large, different types of shock absorbers in the same series can be used to make each shock absorber have the same deformation under different loads;
6. For the bracing isolation system, the center of gravity of the vibration isolator shall coincide with the center of gravity of the equipment as much as possible.
